13 Νοε 2022 · Learn how hydrogen bonding, the attraction between the positive and negative ends of water molecules, explains the unusual properties of water. Explore the effects of hydrogen bonding on boiling point, surface tension, density, and more.
30 Ιαν 2023 · Learn about hydrogen bonding, a special type of dipole-dipole attraction that occurs between molecules with hydrogen atoms bonded to electronegative atoms and lone pairs of electrons. See examples of hydrogen bonding in water, ammonia, and hydrogen fluoride, and how it affects their boiling points.
A hydrogen bond is an electrostatic force of attraction between a hydrogen atom covalently bonded to a more electronegative atom and another electronegative atom with a lone pair. Learn how hydrogen bonds occur in water and other molecules, and how they affect their properties and structures.

Learn about the dynamic and cooperative nature of hydrogen bonding in water, the most important hydrogen-bonded substance. Explore the properties, effects and applications of water hydrogen bonds, such as water dimer, water and life, information transfer, and solubility.
Learn how hydrogen bonds form between water molecules and how they affect water's physical and chemical properties. Find out how water can dissolve ionic and polar compounds, but not non-polar ones.
24 Οκτ 2024 · Furthermore, H-bonds between water molecules manifest themselves via a translational displacement, the H-bond stretch mode, which is a direct probe of H-bond strength. Because this vibrational mode occurs at a low frequency (~200 cm −1 ), close to the thermal energy (1 kT = 207 cm −1 at room temperature), it is difficult to detect.
